The main goal here is splitting the PDF file. After splitting the first page, you can keep adding pages to it until it reaches the size you need. Then you need to start splitting to a new file. Using LEADTOOLS the code is simple and similar to this:
string inputfile = @"C:\Users\Public\Documents\LEADTOOLS Images\leadtools.pdf";
string outputpath = @"C:\temp\result";
RasterCodecs codecs = new RasterCodecs();
CodecsImageInfo info = codecs.GetInformation(inputfile, true);
RasterImage sourcefile;
int Splitscount = 1;

//Save the first page
string outputfile =  outputpath + Splitscount.ToString()+".pdf";
sourcefile = codecs.Load(inputfile, 1);
codecs.Save(sourcefile, outputfile, sourcefile.OriginalFormat, sourcefile.BitsPerPixel, 1, 1, 1, CodecsSavePageMode.Append);

for (int i = 2; i<=info.TotalPages;i++)
{
FileInfo fileInfo = new FileInfo(outputfile);
sourcefile = codecs.Load(inputfile, i);

if (fileInfo.Exists)
{
if ((fileInfo.Length / 1048576) < 8) //check if the file size exceeded 8 MB
{
codecs.Save(sourcefile, outputfile, sourcefile.OriginalFormat, sourcefile.BitsPerPixel, 1, 1, 1, CodecsSavePageMode.Append);
}
else
{
Splitscount++;
outputfile = outputpath + Splitscount.ToString() + ".pdf";
codecs.Save(sourcefile, outputfile, sourcefile.OriginalFormat, sourcefile.BitsPerPixel, 1, 1, 1, CodecsSavePageMode.Append);
}
}
}
They also have advanced PDF options, see this link:

Recently I used an online tool that really helped me to split a large PDF file (containing 100 pages) into multiple PDF files. The best thing about the online service is that it allows splitting PDF file by pages. One click PDF split tool can be found here: http://onlinefreeware.net/pdf/Split.aspx
